Description

calibrate_ambient_carbon_linreg

Usage

calibrate_ambient_carbon_linreg(
  amb_data_list,
  caldf,
  outname,
  site,
  file,
  filter_data = TRUE,
  force_to_end = TRUE,
  force_to_beginning = TRUE,
  gap_fill_parameters = FALSE,
  r2_thres = 0.9
)

Arguments

amb_data_list

List containing an ambient d13C dataset. Will include all variables in 000_0x0_xxm. (character)

caldf

Calibration data frame containing gain and offset values for 12C and 13C isotopologues.

outname

Output variable name. Inherited from calibrate_ambient_carbon_linreg

site

Four-letter NEON code corresponding to site being processed.

file

Output file name. Inherited from calibrate_ambient_carbon_linreg

filter_data

Apply median absolute deviation filter from Brock 86 to remove impulse spikes? Inherited from calibrate_ambient_carbon_linreg

force_to_end

In given month, calibrate ambient data later than last calibration, using the last calibration? (default true)

force_to_beginning

In given month, calibrate ambient data before than first calibration, using the first calibration? (default true)

gap_fill_parameters

Should function attempt to 'gap-fill' across a bad calibration by carrying the last known good calibration forward? Implementation is fairly primitive currently, as it only carries the last known good calibration that's available forward rather than interpolating, etc. Default FALSE.

r2_thres

Minimum r2 value for calibration to be considered "good" and applied to ambient data.

Value

Nothing to environment; returns calibrated ambient observations to the output file. This function is not designed to be called on its own, and is not exported to the namespace.

Rich Fiorella rfiorella@lanl.gov

Function called by calibrate_ambient_carbon_linreg to apply gain and offset parameters to the ambient datasets (000_0x0_09m and 000_0x0_30m). This function should generally not be used independently, but should be used with calibrate_ambient_carbon_linreg.
